Automotive Smoke Machine EVAP Leak Tester, 12V Pump Gauge

Automotive smoke machine leak detector pinpoints EVAP, vacuum, fuel and intake leaks fast, helping you confirm and locate problem spots before parts swapping. Built-in air pump and dual modes let you run quick “leak/no-leak” checks, then switch to smoke tracing for precise location. Real-time pressure and flow readings make it easier to judge leak severity and keep tests consistent across cars, trucks, motorcycles, ATVs and boats.

• Tests EVAP, fuel tank, intake, exhaust, sealing and general hose/pipe leaks on 12V vehicles


• Delivers stable output with a built-in air pump—no external compressor needed


• Switches between Air Mode for verification and Smoke Mode to trace the exact leak point


• Monitors pressure and flow in real time to help assess leak size and control output


• Includes adapters, plugs and tools to match common ports and fittings for faster setup

Designed for workshop-level diagnostics in a compact unit, this smoke leak tester supports repeatable checks across multiple systems and vehicle types. Use the flow control knob to fine-tune output for small lines or larger volumes, and watch the gauges to keep each test within your target range. Add 10–20 ml of baby oil or mineral oil (not included) before smoke testing. Stock your garage with a reliable way to verify repairs and catch hidden leaks—grab yours today.
